The Review of Raspberry Pi Based - Systems to Assist the Disabled Persons

As people, eyesight is one of the most significant and depended upon in acquainting ourselves with where we are and what is around us. Freedom in exploring our new environment has to do with our capacity to survey these new environments, distinguish impediments as well as distinguish between objects in these environments. This task as simple as it may seem is one of the many problems encountered by the blind in their daily lives. Which hinders their ability to freely move about and carry out their day-to-day activities. Many types of research have been carried out to develop systems to assist the blind and the deaf. Some of these researches were developed with microcomputers as their central component. This study seeks to investigate the literature for studies that utilized raspberry pi to develop systems to assist the blind and the deaf. It as well attempts to define future research perspectives on the subject by addressing the research questions stated in this study. The finding of this study would enlighten researchers to be guided for future researches, as well as enable them to see the flaws in the area of study in other to solve such problems.
